SCADA – PLC modbus communication

Connecting PLC in industrial environment with SCADA systems using Software Defined Wide Area Networks (SD-WAN), GWG 3G/4G Gateway and mobile technologies. In this project, we used SIM cards from one of the global mobile providers with coverage in many countries and its SD-WAN solution based on the cloud because it is easy to deploy and user friendly with a high level of automation.

High Speed System Implementation - Video Surveillance

 
GWR introduction
 

GWR routers represent a robust solution designed to provide remote connectivity via cellular networks. Low transmission delay and very high data rates powered by existing cellular networks completely eliminate the need for expensive wired infrastructure. GWR series brings scalability of even most demanding corporate networks on highest possible level. Installing a reliable, high performance backup solution for existing land lines or satellite networks is now a simple task thanks to modern cellular networks. Therefore, no matter if the goal is to provide primary internet access or backup solution for already existing network GWR router series represents a top rated solution.

 

So many useful features make GWR routers a perfect solution for wide range of reliable applications:

 

Dual SIM card support increases the reliability of the router and provides a solution for those applications where failure of one mobile network must not result in system downtime. Automatic failover feature will detect the failure of primary connection and automatically switch to alternative connection. When the connectivity over primary connection is restored GWR router will perform switchover to primary connection.

 

The whole set of advanced WAN settings allow a user to specify desired parameters in order to meet the requirements of specific cellular network. GWR routers proved themselves to be reliable and high performance devices in so many countries around the world. All advanced parameters included represent the result of detailed analysis of large number of different cellular networks. In few simple steps it is possible to optimize the performance of the router on almost any cellular network.

 

VPN, IPSec or OpenVPN, tunnel support provides powerful options for network expansion and secure data transfer over the cellular network.

Importance of reliability
 
The complete series inherited the basic concept of GWR router – Reliability Comes First. Therefore all routers models have dual SIM card support. There are a number of reasons why service reliability is an important product attribute, including:
 
Reputation. Reputation is very closely related to the reliability of services. The more reliable a service is the more likely is to have a favorable reputation.
 
Customer Satisfaction. While a reliable service may not dramatically affect customer satisfaction in a positive manner, an unreliable product will negatively affect customer satisfaction severely. Thus high reliability is a mandatory requirement for customer satisfaction.
 
Warranty Costs. If a service fails to perform its function, the costs of service downtime will negatively affect profits, as well as gain unwanted negative attention. Introducing reliability analyses is an important step in taking corrective action, ultimately leading to a service that is more reliable.
 
Repeat Business. A concentrated effort towards improved reliability shows existing customers that service provider is serious about their service, and committed to customer satisfaction. This type of attitude has a positive impact on future business.
 
Cost Analysis. Service provider may take reliability data and combine it with other cost information to illustrate the cost-effectiveness of their products. This life cycle cost analysis can prove that although the initial cost of their services might be higher, the overall lifetime cost is lower than a competitor's because their services has minimum downtime and requires less maintenance.
 
Competitive Advantage. Many competitors will publish their predicted reliability numbers to help gain an advantage over their competition who either does not publish their numbers or has lower numbers.
 
 
Solution
 
In the world of vast security challenges the ability to cover every location with video surveillance (CCTV) is of high importance. For such mission video surveillance systems mostly utilize IP-based cameras. Cellular network is used for communication to decrease costs and to utilize remote monitoring flexibility.
 
Mobile providers are constantly launching faster 3G/4G mobile broadband technologies for communication services. There is a simple way to connect video surveillance systems to new high-speed 3G/4G cellular data networks. The convergence of these trends is rapidly expanding the number of situations where video security applications can be deployed quickly and effectively.
 
Configuration example
 
In the following scenario Geneko GWR402 cellular router is exploited in high available system where dual SIM option is used. With LTE network the effective throughput is on much higher level and it corresponds to high-definition demands. Video camera can be connected by wire over Ethernet interface or using WiFi. GWR402 is used as access point which collects wireless client and provide internet access. This provides flexible implementation which customer can easily modify according to specific requirements.
 
 
On the other hand reliability is achieved with two SIM cards where one overtakes PPP connection from the other in case of need. SIM cards cannot be connected at the same time; second SIM card provides only back-up link in the case first SIM card drops the connection.
 
Following picture shows system with one central location with HQ router and several remote locations with GWR402 routers. Communication between local and remote LAN is conducted through LTE network.
 
Central location can communicate with multiple remote locations. Every location can be configured in similar way. DVR Server, which collects data from video cameras, is located at the central location inside DMZ zone of HQ router.
